Error opening Webdynpro view of NWDS 7.3

[Former Member]

I just installed NWDS 7.3 patch 1. Installed JDK 1.6.0_07.  NWDS is  having problem showing Webdynpro view.  When i open the webdynpro view and drag a UI control all i get is the below screen.

In the error log i get the below error message. I was able to compile and deploy the DC, but having problem see the webdynpro view in the Studio. Please help on what need to be done. I tried this on Windows XP and Windows 7 , and ran into the exact same issue.

Hi ,

I think your Jdk is not compatible with the NWDS version so please change it to 32 bit JDK and try.

I think this will sure work .

Thanks & Regards,
